Avila, the collaborative project of Daniel Johnson and Brie Stoner, recently released an EP of covers called Curtains. Their songs have been getting them some attention due to their use in some big commercials. This one, a cover of Elvis' "All Shook Up," was featured in a Trojan commercial, and listeners were intent on finding who did the song. Their version is a slow, somewhat ethereal version of the classic rock n' roll song.
You can get Avila's EP, Curtains, on iTunes.
